Fixed platform.This type of rig is built on steel or concrete legs anchored directly onto the seabed,supporting a deck with space for drilling rigs,production facilities and crew quarters.Such building are,by virtue of their immobility,designed for very long term use.Tension-Leg Platforms - an overview ScienceDirect TopicsThis uses the piles driven into the seabed as an anchor,thus the name anchor pile.The bottom of each tension leg has an anchor connector and a lower flexible device,the former providing automatic mechanical locking to fix the tension leg on the anchor pile and the latter allowing the tension leg to move relative to the locking device for oblique movement.Tanks Specs Drawings - Caldwell TanksComposite Elevated Storage Tank (CET) Multi-Column Elevated Storage Tank (LEG) Pedesphere Elevated Storage Tank (PED) Fluted Column Elevated Storage Tank (FLC) Ground Supported Flat Bottom Storage Tank (FB) Click the icons to download files.Document Formats = DOC = PDF = DWG.
